Functional description

5.1 Drive unit
The metering pump is an diaphragm pump, the stroke length of which can
be adjusted. An electric motor (1) drives the pump. A worm gear (2) steps
down its drive rotation A cam (3), in conjunction with the uptake fork (8)
converts this into an oscillation movement of the slide rod (4). A return
spring (5) presses the uptake fork together with the slide rod positively
against the cam thus producing the reciprocal stroke. The stroke length
can be adjusted using the stroke adjustment dial (6) and the axle (7). The
different stroke lengths are in effect caused by a limitation of the reciprocal
strokes (see Ä “Illustration of the stroke movement” on page 15). The
slide rod transmits the stoke motion to the metering diaphragms.

5.2 Liquid end
The diaphragm (2) hermetically shuts off the pump volume of the dosing
head (4) towards the outside. The suction valve (1) closes as soon as the
diaphragm (2) is moved in to the dosing head (4) and the feed chemical
flows through the discharge valve (3) out of the dosing head. The dis‐
charge valve (3) closes as soon as the diaphragm (2) is moved in the
opposite direction due to the vacuum pressure in the dosing head and
fresh feed chemical flows through the suction valve (1) into the dosing
head. One cycle is thus completed.

5.3 Integral relief valve
The integral relief valve normally operates as a simple, directly controlled
bleeder valve. As soon as the pressure exceeds the pressure value, which
is set using the large spring (1), it lifts the ball (2). The feed chemical then
flows out through the hose connection (5), e.g. into a storage tank.
The integral relief valve can only protect the motor and the gear, and then
only against impermissible positive pressure that is caused by the
metering pump itself. It cannot protect the system against positive pres‐
sure.
The integral relief valve works as a bleed valve if the rotary dial (3) is
turned clockwise up to the "open" stop: This relieves the high force caused

by the large spring (1) which was acting on the ball (2) - the ball is now
controlled by the low force of the small spring (4). The integral relief valve
is, when used in this way, a priming aid for starting up the pump against
pressure.

5.4 Multi-layer safety diaphragm
The multi-layer safety diaphragm has the same function as the conven‐
tional double diaphragm system with working and safety diaphragms; how‐
ever it also has the advantage that both diaphragms are joined together in
a single unit.
If the working layer (1) breaks, the feed chemical penetrates between the
working and safety (2) layers and spreads out. The safety layer ensures
that not feed chemical penetrates to the outside.
As soon as the feed chemical reaches the flap (3) on the edge of the multilayer safety diaphragm, it inflates it. The flap presses a piston (4) in the
membrane rupture sensor (5), so that this triggers.
With the visual diaphragm rupture sensor, the lowered red cylinder (6)
springs forward beneath the transparent cover (7) so that it then becomes
clearly visibleFig. 9.
With the electrical diaphragm rupture sensor, a switch is switched. A con‐
nected signalling device must signal the diaphragm rupture.

Fig. 9: Visual diaphragm rupture sensor, triggered and untriggered
The electrical diaphragm rupture sensor is connected to the "diaphragm
rupture indicator" terminal. If a diaphragm rupture occurs, the red LED
“Fault” indicator illuminates on the pump, the identifier “Error” and
“DIAPH” flash on the LCD screen. Dependent on the identity code variant
selected under "Displacement body", the pump either continues metering
( “Pump emits alarm” ) or stops ( “Pump stops” ).

5.5 Operating modes
The operating modes are selected via the “MODE” menu (dependent on
the identity code, some operating modes may not be present):

“Analog” operating mode (Identity code, control variant: analog). The
stroke rate is controlled using an analog current signal via the "External
control" terminal Processing of the current signal can be preselected via
the control unit.
“Manual” operating mode The stroke rate is set manually via the control
unit. 100 % corresponds to 180 strokes/min.
“Contact” operating mode: This operating mode provides the option of
making fine adjustments using small scaling or transfer factors. The
metering can be triggered either by a pulse received via the "External con‐
trol" terminal or through a contact or a semiconductor switching element. A
metering quantity (batch) or a number of strokes (scaling or transfer factor
0.01 to 99.99) can be pre-selected via the control unit using the "Pulse
Control" option.
“Batch” operating mode: This operating mode provides the option of
working with large transfer factors (up to 65535). The metering can be trig‐
gered either by pressing the [P] key or by a pulse received via the
"External control" terminal or through a contact or a semiconductor
switching element. It is possible to pre-select a metering quantity (batch)
or a number of strokes via the control unit.
“BUS” operating mode (Identity code, control variant: CANopen or PRO‐
FIBUS® This operating mode provides the option of controlling the pump
via a BUS (see “Supplementary instructions for ProMinent® gamma/ L and

ProMinent Sigma versions with PROFIBUS®".

18


Functional description

5.6 Functions
The following functions can be selected using the SET menu:
"Calibrate" function: (Identity code, stroke length adjustment: manual +
calibration) The pump can also be operated in the calibrated state in all
operating modes. In this case, the corresponding continuous displays can
then indicate the metering volume or the capacity directly. Calibration is
maintained within a stroke rate range of 0 - 180 strokes/min. The calibra‐
tion is also maintained when the stroke length is altered by up to ±10 %
scale divisions.
"Auxiliary frequency" function: Enables a freely selectable and program‐
mable stroke rate to be switched on in the “SET” menu, which can be
controlled via the "External Control" terminal. This auxiliary frequency has
priority over the operating mode stroke rate settings .
"Flow" function: Stops the pump when the flow is insufficient, provided a
dosing monitor is connected. The number of defective strokes, after which
the pump is switched off, can be set in the “SET” menu.
The following functions are available as standard:
"Level switch" function: Information about the liquid level in the chemical
feed container is reported to the pump control. To do so, a two-stage level
switch must be fitted; it is connected to the "Level switch" terminal.
"Pause" function: The pump can be remotely stopped via the "External
Control" terminal. The "Pause" function only works via the "External Con‐
trol" terminal.

The following functions are triggered by a key press:
"Stop" function: The pump can be stopped without disconnecting it from
the power supply by pressing the [STOP/START] key.
"Prime" function: Priming (short-term transport at maximum frequency) can
be triggered by simultaneous pressing of the two arrow keys in the "Stroke
rate" continuous display.

5.7 Options
Relay option

The pump has two connecting options (not with PROFIBUS® or timer):
Option "Fault indicating relay" or "Power relay": In the event of fault sig‐
nals, warning signals or tripped level switches, the relay connects to com‐
plete an electric circuit (for alarm horns etc.). The relay can be retrofitted
via a knock-out in the drive unit.
"Fault indicating and pacing relay" option In addition to the fault indicating
relay, the pacing relay can be used to make a contact every stroke. The
relay can be retrofitted via a knock-out in the drive unit.

19


Functional description

5.8 Function and fault Indicator
The operating and fault statuses are indicated by the three LED indicators
and the “Error” identifier on the LCD screen, see also the "Trouble‐
shooting" chapter.

5.9 LCD screen

If a fault occurs, the identifier “Error” appears and an additional error mes‐
sage.

5.10

LED indicators
Operating indicator (green): The operating indicator illuminates if during
pump operation there are no incoming fault or warning messages. It goes
out briefly with every stroke.
Warning indicator (yellow): The warning indicator illuminates, if the pump
electronics detect a condition which may lead to a fault, e.g. "liquid level
low 1st stage".
Fault indicator (red): The fault indicator illuminates, if a fault occurs e.g.
liquid level low 2nd stage".

5.11

Hierarchy of operating modes, functions and fault statuses
The different operating modes, functions and fault statuses have a dif‐
ferent effect on if and how the pump reacts.
The following list shows the order:
1. - Priming
2. - Fault, Stop, Pause
3. - Auxiliary frequency (external frequency changeover)

Installation
CAUTION!
Danger of personnel injury and material damage
The disregard of technical data during installation may lead
to personal injuries or damage to property.
–

Observe the technical data- refer to chapter "Technical
Data" and, where applicable, the operating instructions
of the accessories.

7.1 Installation, hydraulic
WARNING!
Warning of feed chemical reactions to water
Feed chemicals that should not come into contact with water
may react to residual water in the liquid end that may origi‐
nate from works testing.
–
–

Blow the liquid end dry with compressed air through the
suction connector.
Then flush the liquid end with a suitable medium through
the suction connector.


WARNING!
The following measures are an advantage when working with
highly aggressive or hazardous feed chemicals:
–
–

Install a bleed valve with recirculation in the storage
tank.
Install an additional shut-off valve on the discharge or
suction ends.

CAUTION!
Warning about personal and material damage
Also observe the "General Operating Instructions for ProMi‐
nent ® Motor-Driven Metering Pumps and Hydraulic Accesso‐
ries"!

CAUTION!
Suction problems possible
For feed chemicals with a particle size greater than 0.3 mm,
the valves may no longer close properly.
–

Install a suitable filter in the suction line.

23


Installation


CAUTION!
Warning against the discharge line bursting
With a closed discharge line (e.g. due to a clogged discharge
line or by closing a valve), the pressure that the metering
pump generates can reach several times the permissible
pressure of the system or the metering pump. This could
lead to lines bursting resulting in dangerous consequences
with aggressive or toxic feed chemicals.
–

Install a relief valve that limits the pressure of the pump
to the maximum permissible operating pressure of the
system.

CAUTION!
Warning against bursting of the suction or discharge lines
Hose lines with insufficient pressure rating may burst.
–

Only use hose lines with the required pressure rating.

CAUTION!
Warning against lines disconnecting
With suction, discharge and relief lines installed incorrectly
can loosen / disconnect from the pump connection.
–
–
–


Only use original hoses with the specified hose diameter
and wall thickness.
Only use clamping rings and hose nozzles that corre‐
spond with the respective hose diameter.
Always connect the lines without mechanical tension.

CAUTION!
Warning against leaks
Leaks can occur on the pump connection depending on the
insert used.

P_SI_0021

Fig. 15: Moulded composite seals with
corrugated insert

–

The pump is supplied with PTFE moulded composite
seals with a flare, which are used for the pump connec‐
tions. They seal the connections between grooved pump
valves and the grooved inserts from ProMinent - see
Fig. 15.
In the event that an unflared insert is used (e.g. third
party part), an elastomer flat seal must be used - see
Fig. 16.

Numerous installation instructions with drawings are con‐
tained in the "General Operating Instructions for ProMinent®
metering pumps and hydraulic accessories".

–
–

Precise metering is only possible when the back pres‐
sure is maintained above 1 bar at all times.
If metering at atmospheric pressure, a back pressure
valve should be used to create a back pressure of
approx. 1.5 bar.


Installation

CAUTION!
Warning of backflow
A back pressure valve, spring-loaded injection valve, relief
valve, foot valve or a liquid end do not represent absolutely
leak-tight closing elements.
–

For this purpose use a shut-off valve, a solenoid valve or
a vacuum breaker.


CAUTION!
Warning of illegal operation
Observe the regulations that apply where the unit is to be
installed.

CAUTION!
To check the pressure conditions in the piping system it is
recommended that connecting options are provided for a
manometer close to the suction and pressure connector.

Integral relief valve

CAUTION!
Danger due to incorrect use of the integral relief valve
The integral relief valve can only protect the motor and the
gear, and then only against impermissible positive pressure
that is caused by the metering pump itself. It cannot protect
the system against positive pressure.
–
–

Protect the motor and gear of the system against posi‐
tive pressure using other mechanisms.
Protect the system against illegal positive pressure using
other mechanisms.
